Beam disappearing in "beam mode"

When I use the advanced abstract creator to create a tunnel (circle) made of beams (not lines) and make it spin (set beam speed); one of the beams keeps disappearing for a short amount of time.

If I make the tunnel move clockwise, the beam disappears around the 45 minute mark and turns back on just past the hour mark. If you move it counter-clockwise it happens the other way around. Changing the amound of beams or size or adjusting the rotation speed doesn't seem to change this.

It also happens in cue 25 under the "cones" tab in the atmospherics section.

I would make sure the position of the cue object is centered. If it is off even a bit it will cause some of the points to go out of the drawing area if you are rotating the cue which will make those points "disappear".

Notice that on the right side, the beams overlap, even when the circle is divided into equal parts. If you play with the "repeat" knob, and take 4 repeats, it will end. All other settings ( also with beams ) will give this overlap effect. ( if I repeat it with a whole digit, it should not do that )
If I copy the workspace back to my working system, everything works again, as it should.
